Stainless Steel 316 Marine Water Plug: 38x50mm Corrosion Resistant Drainage Fitting

This corrosion resistant stainless steel water plug provides a durable solution for marine drainage applications on ships and yachts. Designed specifically for bilge systems and deck scupper fittings, the plug offers reliable performance in saltwater environments. With dimensions measuring 4.5 centimetres by 5.5 centimetres by 2.0 centimetres, it fits standard marine drainage points while maintaining effective sealing against water ingress. The use of stainless steel 316 ensures enhanced resistance to chloride corrosion compared to standard stainless grades, making it suitable for extended marine service.

Features and Construction

This marine water plug combines specific dimensional specifications with material selection optimised for saltwater environments. The product's construction focuses on practical marine applications where corrosion resistance and reliable sealing are primary considerations.

Material and Build

The water plug is constructed entirely from stainless steel 316, a chromium-nickel-molybdenum austenitic stainless steel alloy. This material selection provides improved resistance to pitting and crevice corrosion in chloride-containing environments compared to standard 304 stainless steel. The absence of plastic or rubber components in the construction indicates a metal-to-metal sealing approach, suitable for marine applications where long-term durability in harsh conditions is required.

Size and Practical Fit

With dimensions of 4.5cm length, 5.5cm width, and 2.0cm thickness, this water plug offers a specific dimensional profile for marine installations. The 38x50mm model designation suggests compatibility with standard marine drainage fittings, though exact compatibility should be verified against specific vessel requirements. The compact dimensions allow installation in confined bilge spaces while maintaining sufficient surface area for effective sealing against water pressure.

Uses and Placement

This water plug serves specific functions in marine environments where controlled drainage and water management are essential for vessel operation and safety.

Marine Vessel Applications

Designed specifically for ships and yachts, this water plug finds application in bilge drainage systems where temporary or permanent sealing of drainage points is required. It can serve in deck scupper fittings to prevent water ingress while allowing controlled drainage during normal operations. The stainless steel construction makes it suitable for both above-water and below-water line applications where corrosion resistance is critical.

Installation Considerations

The water plug's dimensions of 4.5cm x 5.5cm x 2.0cm suggest installation in pre-existing marine drainage fittings of corresponding size. Proper installation requires clean mating surfaces and appropriate fastening methods according to marine engineering standards. The absence of specific installation hardware in the product description indicates that installation components may need to be sourced separately based on specific vessel requirements.

Benefits and Buying Value

This marine water plug offers practical advantages for vessel owners and marine engineers seeking reliable drainage solutions.

Corrosion Resistance and Maintenance

The stainless steel 316 construction provides inherent corrosion resistance in marine environments, reducing maintenance requirements compared to lesser-grade materials. This material selection helps prevent the degradation that can occur with prolonged exposure to saltwater, potentially extending service life in harsh marine conditions. The all-metal construction minimises components that might degrade from UV exposure or marine organisms.

Why Choose This Product

This water plug offers specific dimensional specifications (4.5cm x 5.5cm x 2.0cm) combined with marine-grade stainless steel 316 construction. The clear model identification (water plug 38 * 50) facilitates accurate ordering and replacement. For marine applications where corrosion resistance and reliable sealing are priorities, this product provides a purpose-built solution without unnecessary complexity or components that might fail in marine environments.
